There wasn't anything stopping compilers from doing it in release builds either, but most optimizations would make the padding zero

Pokechu22 bdcfb31187 VideoCommon: Handle custom texture sizes correctly
Specifically, when using Manual Texture Sampling, if textures sizes don't match the size the game specifies, things previously broke.  That can happen with custom textures, and also with scaled EFB copies at non-native IRs.  It breaks most obviously by not scaling the texture coordinates (so only part of the texture shows up), but the hardware wrapping functionality also assumes texture sizes are a power of 2 (or else it will behave weirdly in a way that matches how hardware behaves weirdly).  The fix is to provide alternative texture wrapping logic when custom texture sizes are possible.

Pokechu22 52c82733f6 Use custom isnan implementation to avoid HLSL optimizer issues
This adjusts the NaN replacement logic introduced in #9928 to work around the HLSL compiler optimizing away calls to isnan, which caused that functionality to not work with ubershaders on D3D11 and D3D12 (it did work with specialized shaders, despite a warning being logged for both; that warning is also now gone).  Note that the `D3DCOMPILE_IEEE_STRICTNESS` flag did not solve this issue, despite the warning suggesting that it might.

Suggested by @kayru and @jamiehayes.

Stenzek 51724c1ccd LightingShaderGen: Always calculate lighting for both color channels
Cel-damage depends on lighting being calculated for the first channel
even though there is no color in the vertex format (defaults to the
material color). If lighting for the channel is not enabled, the vertex
will use the default color as before.

The default value of the color is determined by the number of elements in
the vertex format. This fixes the grey cubes in Super Mario Sunshine.

If the color channel count is zero, we set the color to black before the
end of the vertex shader. It's possible that this would be undefined
behavior on hardware if a vertex color index that was greater than the
channel count was used within TEV.

Lioncash a5b28f1f07 ShaderGenCommon: Rename WriteFmt() to Write()
Now that we've converted all of the shader generators over to using fmt,
we can drop the old Write() member function and perform a rename
operation on the WriteFmt() to turn it into the new Write() function.

All changes within this are the removal of a <cstdarg> header, since the
previous printf-based Write() required it, and renaming. No functional
changes are made at all.

Lioncash 86f8768268 VideoCommon/ShaderGenCommon: Make template functions regular functions
These are only ever used with ShaderCode instances and nothing else.
Given that, we can convert these helper functions to expect that type of
object as an argument and remove the need for templates, improving
compiler throughput a marginal amount, as the template instantiation
process doesn't need to be performed.

We can also move the definitions of these functions into the cpp file,
which allows us to remove a few inclusions from the ShaderGenCommon
header. This uncovered a few instances of indirect inclusions being
relied upon in other source files.

One other benefit is this allows changes to be made to the definitions
of the functions without needing to recompile all translation units that
make use of these functions, making change testing a little quicker.

Moving the definitions into the cpp file also allows us to completely
hide DefineOutputMember() from external view, given it's only ever used
inside of GenerateVSOutputMembers().

Lioncash e3506ff4ef VideoCommon/ShaderGenCommon: Convert helper functions over to fmt
A very trivial conversion, this simply converts calls to Write over to
WriteFmt and adjusts the formatting specifiers as necessary.

This also allows the const char* parameters to become std::string_view
instances, allowing for ease of use with other string types.

Lioncash 8af6bfb8b0 VideoCommon/ShaderGenCommon: Add function for writing fmt-based strings
Begins the conversion of the shader generators over to using fmt
formatting specifiers.

This also has a benefit over the older StringFromFormat-based API in
that all formatted data is appended to the existing buffer rather than
creating a completely separate string and then appending it to the
internal string buffer.

Lioncash f7eff6dab8 VideoCommon/ShaderGenCommon: Simplify operator!= for ShaderUid

Lioncash 954246d10e VideoCommon/ShaderGenCommon: Remove use of a union within ShaderUid
This is only ever used to retrieve a raw view of the given UID data
structure, however it's already valid C++ to retrieve a char/unsigned
char view of an object for bytewise inspection.

u8 maps to unsigned char on all platforms we support, so we can just do
this directly with a reinterpret cast, simplifying the overall
interface.

Lioncash 149a97e396 VideoCommon: Remove unnecessary memset on ShaderUid instances.
Zero-initialization zeroes out all members and padding bits, so this is
safe to do. While we're at it, also add static assertions that enforce
the necessary requirements of a UID type explicitly within the ShaderUid
class.

This way, we can remove several memset calls around the shader
generation code that makes sure the underlying UID data is zeroed out.
Now our ShaderUid class enforces this for us, so we don't need to care about
it at the usage sites.
